You might as well just ask people to square 25.

Only way it has a chance close to nil of being tricky is if you don't know the associative property of addition.Meaning, $(a + b) + c = a + (b + c)$ in this case, adding both a and c together would cancel out, giving the result of $25$ but as it's an already given constant, the result would always be the same: $25^{2} = 625$
Otherwise, it's a more or less a giveaway question.

think any number, add 25 to your number and then substract with the number you thought :v

(x + 25 - x)^2 = 625

(X)+25 X+25-X (X-X)+25 25*25 =625

// Algorithm:

any_number, result // can be int, float, double

any_number + 25 // useless line, makes things complicated

result = (any number + 25) - any number // makes things even more complicated

/*

* line above ^ can be reduced to "result = 25;"

*

* result = (any number + 25) - any number

* result - 25 = any number - any number

* result - 25 = 0

* result = 25

*/

square result; // square of 25 is 625 since 25*25 = 625

// therefore it always ends up with 625.

really dude and here i was thinking it was something cool

This is what happens before squaring if your number is $a$ the equation is $a + 25 - a$ you can cross out the two $a$ and you get that you have to square 25. And 25 squared = $25^2$ = 625.

actually this question can be modified as 25 square

So easy lets take the number you selected as x. So first step is x+25. Second is to do x+25-x. This gives us just 25. At the end square 25 to get 625.

Any number + 25 - the number = 25; 25^2 = 625

Hey, think of a number, add 1, remove 1, and the answer is the number you thought of :) MAGIC.

Probably the worst "Think of a Number" problem I've ever seen.

It doesn't matter which number you think of, because you are basically just adding and then subtracting it from 25. So you are basically just squaring 25.

25^2=625

let the number be x . then (x + 25 - x)^2 is the required number. so it becomes 25^2 = 625

Whatever may the number you think of when you substract the number the number become 25 anyways so square of 25 is 625

x + 25 - x = 25

(25)^2 = 625

Is that a question? How funny

The answer is: (x+25-x)² = (25)²= 625.

1. Think in any number: n .
2. ( n + 25 - n )² = X
3. (25)² = X = 625

think the number is "A"

so (A+25-A)^2 = the answer is always (25)^2 = 625

$(x+25-x) ^ 2=(x-x+25) ^ 2=(0+25) ^ 2=25 ^ 2=625$

Bakvas ques Just add any no and subtract it . 625

{(x+25) - x } ^2 =25^2 = 625 ; step 1 : x ; step 2 : x+25 ; step 3 : (x+25) - x = 25 ; step 4 : {(x+25) - x}^2 = 25^2 = 625 ;

x=the no. (x+25-x)^2=625

That was a little tricky. But as it was written Think of any number, I thought of 0 as the no.

if we say that we have a number . and if we add 25 to the number and then again subtract the the chosen number , we will only get 25 as the answer . at the final part of the question we have to find the square of the number . so square of 25 will become 625 resulting as the answer

that's tricky.
